Question

Calculate the median of the following items :
15,23,20,20,23,35,26,27,25,40

Answer 1

The data is first arranged in ascending order :

M= size of `((N+1)/(2))` th item
=Size of `((10+1)/(2))` th item = Size of 5.5th item
`=("Size of 5th item + Size of 6th item")/(2)`
` :. =(23+25)/(2)=(48)/(2)=24`
Median = 24.
